Ben Horowitz

Horowitz was born Benjamin Abraham Horowitz in London, England and raised in Berkeley, California, the son of Elissa Krauthamer and conservative writer and policy advocate David Horowitz. Horowitz's great-grandparents were Jewish immigrants from the Russian Empire who arrived in the U.S. in the mid-19th and early 20th centuries.

On July 6, 2009, Horowitz and Andreessen launched Andreessen Horowitz, to invest in and advise both early-stage startups and more established growth companies in high technology. Andreessen Horowitz began with an initial capitalization of $300 million and within three years had $2.7 billion under management across three funds.

In June 2002, Horowitz began a transformation of Loudcloud into Opsware, an enterprise software company. He took the first step by selling Loudcloud's core managed services business to Electronic Data Systems for $63.5 million in cash. This transaction transferred 100% of Loudcloud's revenue to EDS while the company was publicly traded on NASDAQ. Beginning with EDS as its first enterprise software customer, Horowitz grew Opsware to hundreds of enterprise customers, over $100 million in annual revenue, and 550 employees. In July 2007, Horowitz sold Opsware to Hewlett-Packard for $1.6 billion in cash.

In September 1999, Horowitz cofounded Loudcloud with Andreessen, Tim Howes, and In Sik Rhee. Loudcloud offered infrastructure and application hosting services to enterprise and Internet customers such as Ford Motor Company, Nike, Inc., Gannett Company, News Corporation, the United States Army and other large organizations. Horowitz took Loudcloud public on March 9, 2001.

Horowitz began his career as an engineer at Silicon Graphics in 1990. In 1995, Horowitz joined Marc Andreessen at Netscape as a product manager. From 1997 to 1998, Horowitz was vice president for the Directory and Security Product Line at Netscape. After Netscape was acquired by AOL in 1998, Horowitz served as Vice President of AOL's eCommerce Division.

Horowitz earned a BA in Computer Science from Columbia University in 1988 and an MS in Computer Science from UCLA in 1990.

Horowitz lives in Atherton, California with his wife, Felicia Wiley Horowitz. They married in 1988 and have three children.
